future 45k investment advice

By the end of this year I plan to have $45,000 AUD saved up in total, covering the majority of my uni expenses before even starting.

However none of this covers my rent (roughly 300-350 pw)

Wanted some advice from people much more crypto-savvy than I am. How realistic is it if I put a majority of my savings into really basic crypto holdings (moreso 'investing' than 'trading') and being able to generate at least 300pw then auto-pulling to avoid risk? (Assume im not spending the money on uni yet for simplicity)

For the sake of hypotheticals, if I put all 45,000 in, 300 is only 0.67% in a single day.

Is this reliable? And do people do things similar? Any advice or information is EXTREMELY helpful! Thank you very much in advance.
